Does anybody else remember the 12 ga home defense ammo they had in the mid 1990s that was a stack of 12 lead discs loaded in a shotgun shell? I was digging through my old ammo and found a package of it and the other version that had notched discs that were supposed to shatter when they hit. The company that made them has long since disappeared, but I was wondering if there was anybody else out there making something like these?
